Construction & Working of a Photodiode - Optical Devices

This EzEd video explains the Construction& Working of a PHOTO DIODE
1) Operated in Reverse Bias Mode
2) Reverse Saturation Current - Photo Current
3) Dark Current
4) Advantages & Disadvantages of Photo Diode

Than u so all doubts clear after watching ur video

[thetechnician]

I would like to build a fire alerting system using a photodiode and my point of concern is on how can I build it in a way that the photodiode responds to fire threats but not other threats like light being emitted by torches, bulbs, LEDs and others of that sort.

Thank you so much can't thank you enough to clear my doubt about reverse bias

[ahmadf]

Does it produce any current without bias? What happens if we just connect a PD to a resistor and shine the light to it? Does the current flow through resistor?

[patrickschwarzenecker]

why is there a voltage source? th photo diode creates curren–> current source

[clg_gurl]

Thank you so much you clarified all of my doubts.

[mohdiqbal]

Which diode works on the principle of photoelectric effect
